    During the transitional phase, the regulators will be checking if other products can be added to the list like for example some downstream products. From the beginning of 2026 importers of products included in these 6 sectors will begin to pay a border carbon tax for their products based on the price of allowances in the European Union ...

  3. Attention (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Attention_(machine_learning)

    In practice, the attention of each word is calculated in parallel to speed up calculations. Simply changing the lowercase "x" vector to the uppercase "X" matrix will yield the formula for this. Softmax scaling qW k T / √ 100 prevents a high variance in qW k T that would allow a single word to excessively dominate the softmax resulting in ...

  4. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The CLTD/CLF/SCL (cooling load temperature difference/cooling load factor/solar cooling load factor) cooling load calculation method was first introduced in the 1979 ASHRAE Cooling and Heating Load Manual (GRP-158) [1] The CLTD/CLF/SCL Method is regarded as a reasonably accurate approximation of the total heat gains through a building envelope ...

  5. Precision and recall - Wikipedia

    en.wikipedia.org/wiki/Precision_and_recall

    To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]

  6. Latent Dirichlet allocation - Wikipedia

    en.wikipedia.org/wiki/Latent_Dirichlet_allocation

    Let , be the number of word tokens in the document with the same word symbol (the word in the vocabulary) assigned to the topic. So, n j , r i {\displaystyle n_{j,r}^{i}} is three dimensional. If any of the three dimensions is not limited to a specific value, we use a parenthesized point ( ⋅ ) {\displaystyle (\cdot )} to denote.

  7. Coleman–Liau index - Wikipedia

    en.wikipedia.org/wiki/Coleman–Liau_index

    The Coleman–Liau index is a readability test designed by Meri Coleman and T. L. Liau to gauge the understandability of a text. Like the Flesch–Kincaid Grade Level, Gunning fog index, SMOG index, and Automated Readability Index, its output approximates the U.S. grade level thought necessary to comprehend the text.

  8. Cost–benefit analysis - Wikipedia

    en.wikipedia.org/wiki/Cost–benefit_analysis

    Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives.It is used to determine options which provide the best approach to achieving benefits while preserving savings in, for example, transactions, activities, and functional business requirements.

  9. OpenDocument technical specification - Wikipedia

    en.wikipedia.org/wiki/OpenDocument_technical...

    OpenDocument exchanges formulas as values of the attribute table:formula. The allowed syntax of table:formula was not defined in sufficient detail in the OpenDocument version 1.0 specification, which defined spreadsheet formulas using a set of simple examples showing, for example, how to specify ranges and the SUM() function.
